Sign in to monitor this recall

Summary

Phibro Animal Health Corporation has recalled 400 bags of Stafac 20 Type A Medicated Article (virginiamycin) because testing showed the medication was not as strong as it should be. The product, used in animal feed, failed potency tests during long-term stability monitoring. This recall affects 50-pound bags with specific lot numbers manufactured in April 2015 and distributed nationwide.

Risk

The medication in these specific lots tested below the required potency specification. If the product is not at full strength, it may not effectively treat or prevent the conditions for which it was prescribed in animals.

What You Should Do

  1. Check your inventory for Stafac 20 Type A Medicated Article in 50-pound (22.6 kg) multi-wall bags.
  2. Identify the lot number on the packaging; the affected lot numbers are N32704049VW and N32764167VW, both with a manufacturing date of April 30, 2015.
  3. Immediately stop using the affected medicated feed and secure it so it is not accidentally used for livestock.
  4. Contact your veterinarian or animal health professional to discuss the impact of using low-potency medication and to determine an appropriate replacement.
